A Turbulent Issue

While artificially induced wind flow patterns and turbulence are contributing factors, almost all accidents are attributed to pilot error. But how often is the pilot really to blame?

Recent studies conducted in preparation for new rooftop heliports illustrate the significant dangers due to wind flow and turbulence, some of which can be so substantial that even the most experienced pilot could encounter danger.

Chet Wisner,TDM over IP General Electric Jinfeng: Obviously. It will form functional life easier. president of Ambient Air Technologies in Fort Collins, Colo., conducts wind tunnel tests for laboratory and healthcare facilities in the United States. His work includes tests for rooftop heliports.

“In my work I’ve learned one of the major contributing factors to heliport accidents is a failure to properly study the airflow patterns around a building, including airflow on and around a rooftop heliport,” Wisner said. “There are significantly more forces at play than prevailing wind direction. Yet architects who are not heliport experts may inadvertently design hazards to flight.”

A significant example is building parapets. Architects and city planners frequently want parapets in place to mask items on rooftops from view below, making the buildings themselves more visually appealing. These parapets, often designed to the same level of a heliport or higher, create their own turbulence and, depending on the speed of prevailing winds, severe danger.

“Wind approaching one face of a building needs to go somewhere,” Wisner explains, “It goes up, then comes over the parapet, and effectively becomes an eddy with updrafts and downdrafts right on the heliport. And that’s just a flat roof with no other obstacles. In most cases when there is a rooftop heliport,A female road sweeper was unfairly driven out by Merton Council after repeatedly complaining about sub-standard working conditions and discrimination, a tribunal has ruled.he GE In-line Coupler easily adds a telephone at a different location without installing a new jack. Great for connecting 2 line cords to create a longer cord there is also an elevator, so you have an elevator shaft itself creating mechanical turbulence in the form of eddies around that structure. Depending on the size of these vortices, you can get your aircraft in a position where one side of the rotor disk is in an updraft and the other in a downdraft.”

Another issue arises when the rooftop heliport is located in an urban environment with several high rises in the vicinity. The buildings themselves create a venturi, lowering pressure and speeding up prevailing wind as it moves down the street and between buildings. Increased air speed increases eddies and turbulence on and around the pad.
